Chemotherapy is the standard treatment for small cell lung cancer (SCLC), but chemotherapy resistance and adverse reactions remain major problems. Although Traditional Chinese Medicine (TCM) is wildly applied for patients with SCLC in China, the evidence of TCM in the treatment for SCLC is limited. To evaluate the efficacy and safety of TCM combined with chemotherapy for patients with SCLC. We conducted a systematic search of PubMed, EMBASE, the Chinese National Knowledge Infrastructure, the VIP Information Database, and the Wanfang Database for randomized-controlled trials (RCTs) that are relevant. The included studies were reviewed by two investigators, with relevant data extracted independently. The effect estimate of interest was the relative risk (RR) or mean difference with 95% confidence intervals (95% CIs). 22 RCTs involving 1887 patients were included in this study. Compared with patients treated with chemotherapy© alone, those with Chinese herbal medicine and chemotherapy (TCM-C) had better therapeutic effects (RR = 1.295, 95% CI 1.205–1.391, P

BackgroundAstragalus-containing traditional Chinese medicine (TCM) is widely used as adjunctive treatment to platinum-based chemotherapy (PBC) in patients with advanced gastric cancer (AGC) in China. However, evidence regarding its efficacy remains limited. This study aimed to evaluate the efficacy and safety of Astragalus-containing TCM combined with PBC in AGC treatment.MethodsWe searched for literature (up to July 19, 2020) in eight electronic databases. The included studies were reviewed by two researchers. The main outcomes were the objective response rate (ORR), disease control rate (DCR), survival rate, quality of life (QOL), adverse drug reactions (ADRs), and peripheral blood lymphocyte levels. The effect estimate of interest was the risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CIs). Trial sequential analysis (TSA) was used to detect the robustness of the primary outcome and to calculate the required information size (RIS). Certainty of the evidence was assessed using the GRADE profiler.ResultsResults based on available literature showed that, compared with patients treated with PBC alone, those treated with Astragalus-containing TCM had a better ORR (RR: 1.24, 95% CI: 1.15–1.34, P < 0.00001), DCR (RR: 1.10, 95% CI: 1.06–1.14, P < 0.00001), 1-year survival rate (RR: 1.41, 95% CI: 1.09–1.82, P = 0.009), 2-year survival rate (RR: 3.13, 95% CI: 1.80–5.46, P < 0.0001), and QOL (RR: 2.03, 95% CI: 1.70–2.43, P < 0.00001 and MD: 12.39, 95% CI: 5.48–19.30, P = 0.0004); higher proportions of CD3+ T cells and CD3+ CD4+ T cells; higher ratio of CD4+/CD8+ T cells; nature killer cells; and lower incidence of ADRs. Subgroup analysis showed that both oral and injection administration of Astragalus-containing TCM increased tumor response. Whether treatment duration was ≥8 weeks or Astragalus-containing TCM could increase tumor response in AGC patients. Furthermore, Astragalus-containing TCM combined with oxaliplatin-based chemotherapy could increase the ORR and DCR; when with cisplatin, it could only increase the ORR.ConclusionCurrent low to moderate evidence revealed that Astragalus-containing TCM combined with PBC had better efficacy and less side effects in the treatment of AGC; however, more high-quality randomized studies are warranted.Systematic Review RegistrationPROSPERO, identifier CRD42020203486.

ObjectiveP-cadherin can act both as a tumour suppressor and an oncogene. The clinical prognostic value of P-cadherin overexpression in breast cancer (BC) remains unclear. We conducted a study-level meta-analysis to determine whether P-cadherin expression can help predict prognosis in BC.MethodsA systematic literature search was performed to review eligible studies and clarify the relationship between P-cadherin overexpression and overall survival (OS), disease-free survival (DFS), pathological features, molecular subtypes and molecular phenotypes in BC.ResultsThirty-one studies including 12 332 patients were included. P-cadherin overexpression was correlated with significantly worse OS (HR=1.77, p<0.00001) than P-cadherin-negative. P-cadherin overexpression could lead to high histological grade (OR=3.33, pConclusionsP-cadherin was found to be associated with invasiveness and metastasis. P-cadherin expression can probably be a useful biomarker for predicting poor survival and may act as an independent prognostic predictor.

Background: Many studies were performed to explore the correlation between taxane-based chemotherapy and the risk of breast cancer-related lymphedema (BCRL), however, with inconsistent results. Hence, the purpose of this study is to evaluate whether taxane-based chemotherapy is a risk factor for BCRL. Methods: A comprehensive systematic search of clinical trials published in the PubMed, Embase and the Cochrane Library databases will be conducted to identify eligible studies up to the date of December 31, 2018. We will employ risk ratios with 95% confidence intervals (95% CIs) to estimate the correlations between taxane-based chemotherapy and BCRL. Meta-analysis will be performed using Stata SE version 12.0 software. Results: The results of this systematic review and meta-analysis will provide a high-quality synthesis of existing evidence of the correlations between taxane-based chemotherapy and the risk of BCRL. Conclusion: The protocol will provide updated evidence for the use of taxane-based chemotherapy in postoperative breast cancer patients. Ethics and dissemination: It is not necessary for ethical approval because it is based on published studies. The protocol will be disseminated in a peer-reviewed journal or presented at a topic-related conference. Trial registration: This systematic review protocol has been registered with a number of CRD42019123989.

Background Increasing studies were performed to explore the prognostic value of E-cadherin in prostatic carcinoma, however, with inconsistent results. Hence, this systematic review is aimed to evaluate the prognostic role of E-cadherin in patients with prostatic carcinoma (PCa). Methods A comprehensive literature search in all available databases will be conducted to identify eligible studies. We will employ hazard ratios (HRs) and 95% confidence intervals (95% CIs) to estimate the correlations between E-cadherin expression and overall survival (OS), disease-free survival (DFS), relapse-free survival (RFS), progression-free survival (PFS) and clinicopathological features. Meta-analysis will be performed using Review Manager (Revman) 5.3.5 software (Cochrane Community, London, United Kingdom) and STATA 14 software (version 14.0; Stata Corp, College Station, TX). Results This study will provide a high-quality synthesis of current evidence of the correlations between snail expression and OS, DFS/RFS, PFS and clinicopathological features. Conclusion The study will provide updated evidence to assess whether the expression of E-cadherin is in association with poor prognosis in patients with PCa. Ethics and dissemination It is not necessary for ethical approval because individuals cannot be identified. The protocol will be disseminated in a peer-reviewed journal or presented at a relevant conference.

INTRODUCTION Pancreatic cancer is one of the most lethal malignancies worldwide. Most patients are diagnosed at an advanced stage, which leads to a poor prognosis and a low survival rate. At present, treatment options for pancreatic cancer are limited, so it is vital to explore new treatments and strategies. Traditional Chinese medicine (TCM) is an important method for cancer prevention and treatment in China. We will conduct a multicenter, prospective cohort study to evaluate the survival and quality of life of patients with advanced pancreatic cancer treated with integrated traditional Chinese and Western medicine, further refine the core pathogenesis of TCM for pancreatic cancer, form a core prescription, and provide clinical data support for the clinical plan of integrated treatment of pancreatic cancer using Chinese and Western medicine; this will aid in the development of the best comprehensive treatment plan for patients. METHODS AND ANALYSIS This study will recruit patients with stage 3 to 4 pancreatic cancer in 12 medical units from April 2019 to June 2020. Patients will be divided into a Western medicine treatment group and an integrated traditional Chinese and Western medicine treatment group, with a total of 148 patients. Overall survival is the main efficacy index, while the secondary efficacy indexes are progression-free survival, tumor markers, TCM symptom grading scale, quality of life assessment, Eastern Cooperative Oncology Group (ECOG) score, and imaging assessment. A follow-up will be performed every 6 weeks ±1 week. The end point is the death of the patient or the end of the study (October 31, 2021). Statistical analysis will be performed using Statistical Packages of Social Sciences software (SPSS). ETHICS AND DISSEMINATION This work was supported by Beijing Municipal Science and Technology Commission and approved by the ethics committee of Guang'anmen Hospital, China Academy of Chinese Medical Sciences (Approval No. 2019-016-KY). All patients will sign a written informed consent prior to data collection. The results will be disseminated through peer-reviewed journals and conference presentations and will be openly shared after completion of the trial. TRIAL REGISTRATION The trial was registered with the Chinese Clinical Trials Registry (ChiCTR1900022632, pre-registration).

Background: Traditional Chinese Medicine (TCM) therapies have been combined with chemotherapy for preventing Recurrence and metastasis in postoperative II to IIIA non-small-cell lung cancer (NSCLC) and the associated better disease-free survival (DFS), but its effects remain elusive. The purpose of this review is to assess the efficacy of TCM therapies as a treatment for postoperative II to IIIA NSCLC. Methods and analysis: Seventh databases will be searched for relevant studies from inception to the present date. We will include randomized controlled trials assessing TCM therapies combined with chemotherapy for preventing Recurrence and metastasis in postoperative II to IIIA NSCLC. The methodological qualities, including the risk of bias, will be evaluated using the Cochrane risk of bias assessment tool, while confidence in the cumulative evidence will be evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Ethics and dissemination: Ethical approval is not required, as this study is based on the review of published research. This review will be published in a peer-reviewed journal and disseminated both electronically and in print. PROSPERO registration number: The protocol for this systematic review has been registered on PROSPERO under the number CRD42019116594.

Background. Aromatase inhibitors (AIs) are used for adjuvant therapy of breast cancer; however AIMSS (AI-Associated Musculoskeletal Symptoms) can negatively affect quality of life and compliance. Most patients in China moved to TCM (traditional Chinese medicine) for help. TB (tiger bone) is used to treat bone disease, whose main ingredients are calcium and collagen. The objective of this study was to evaluate whether the TB prevented AIMSS in postmenopausal women with ER/PR+ breast cancer.Methods. We conducted a randomized, blind, controlled study of comparing TB versus placebo for 12 weeks in postmenopausal women with breast cancer who have taken AI for less than a month. Patients completed the M-BPI, VAS, and FACT-B at baseline, 6 weeks, and 12 weeks. M-BPI and VAS were used as the primary outcomes. FACT-B was used as the secondary outcome. SerumE2and FSH were tested every 6 weeks.Results. Of 70 evaluable cases, 8 of 35 patients (22.9%) developed new or worsening point symptoms in TB group, compared to 21 of 35 (60%) in placebo group (P<0.001). We also found differences between 2 groups in average pain (2 to 5.6), worst pain (3.9 to 8), pain interference severity (1.9 to 5.3), stiffness (2.4 to 6.9), and joint symptom interference (1.8 to 5.7), allP<0.001; similar findings were seen in VAS value (3 to 6.6) at the end of intervention. HRQoL measured by FACT-B (P<0.05) was improved. No change of serum estradiol and FSH between two groups.Conclusions. TB appeared to be effective and safe in the prevention of AIMSS.
